A plurality of sun-ray collecting units connected to one another by parallel links and arranged in rows on first turning axes are supported on a pair of turning frames that can be turned about the first turning axes. Each of a pair of push-pull cables 54 is connected at one end thereof to a cable driving device and at the other end to one of the sun-ray collecting units which are supported in plurality on each of the turning frames. Thus, a space for placement of a sun-ray tracking system can be relatively reduced in size and the turning angle of each of the sun-ray collecting units about the first turning axis can be relatively increased. The sun-ray collecting units can be turned about the second turning axes in a simple structure using a single drive source. |
